We usually get quite a lot of snow cover here in
Southern Manitoba, but often get late frosts after the snow melts which is what
usually kills an iris more often that winter kill. Thank you for all the
info re mulching, etc. We'll see how my 4 new AB's fr last year fare this
winter, plus the 5 new one's I ordered this year.

very cold climates
*** El - if I remember correctly about your climate....you usually have
no snow cover and I am fortunate to have consistent snow cover
which insulates the the 'tender' irises I grow. (arilbreds and TBs). I grow
all my irises in raised beds except for the Japanese irises. I would mulch
your arilbreds during the worst of the cold winter and remove the mulch as
soon as it is practical and keep a watch for late frosts and cover them up. I
have done that as well.***
Elm, thanks for your reply post. I did join the Aril Society and knew
the - and + designation and what they meant
but I wasn't sure if most did. Yes, the regalia is much hardier with the
ancestry coming from much colder climates than the oncos. I knew that 'Persian
Sapphire' had SDB in its parentage and its bloom habit and growth
pattern is most like an SDB than any other arilbreds that I grow.
Strangely enough, 'Omar's Gold' is 1/4 MDB (!) and the rest of it is
various AB. I do grow other OGB - : 'Sajjetta', 'Loudmouth', 'Prairie
Thunder'....these all have SDB somewhere in their background. The
Arilbreds and the SDBs share a bloom season which is good to know for
folks wanting to extend their iris bloom season.
I still have a few TBs in good bloom and the Siberians
continue in peak bloom with the Japanese irises in high green bud. It
looks like they will be early here...usually they start in mid-July.
